In advance of my book release next week, here is an article I did for @chemistryworld.com about the image of “mad scientists”… I’m particularly proud of the article title 🤣 expect many more puns in the book #ChemSky #SciComm www.chemistryworld.com/opinion/expl...

Good article from Richie Kirwan about the Joe Wicks health/protein bar documentary which had plenty of ridiculous dark lab imagery & scaremongering. I also witnessed someone tell a stranger on the #London tube this week that they should check the ingredients of a bar they were eating #SciComm #Food

The 2025 #NobelPrize in Chemistry was awarded today for the development of metal-organic frameworks, molecular sponges with applications in gas storage, water purification and more: www.compoundchem.com/2025/10/08/2...

Infographic on the 2025 Nobel Prize in Chemistry, awarded to Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for the development of metal-organic frameworks. The infographic explains that metal-organic frameworks are molecular sponges built up from metal ions and organic compounds that act as linkers. Small molecules such as gases can move into and out of cavities in these frameworks. The graphic highlights some of the MOFs the laureates have developed and concludes by looking at possible future uses of MOFs, including gas storage and extracting water from air.

A great round up the issues in academic publishing, particularly the metrics. I feel AI is also highlighting these issues since many AI models have been inadvertently trained on retracted papers. Goodhart's law states: "When a measure becomes a target, it ceases to be a good measure." #Research

I've shared this quote before but I'll share it again, as it's one I've been thinking about a lot as I've watched how our oligarchs have been behaving over the past few months.

At a party given by a billionaire on Shelter Island, Kurt Vonnegut informs his pal, Joseph Heller, that their host, a hedge fund manager, had made more money in a single day than Heller had earned from his wildly popular novel Catch-22 over its whole history. Heller responds, “Yes, but I have something he will never have … enough.” Enough. I was stunned by the simple eloquence of that word—stunned for two reasons: first, because I have been given so much in my own life and, second, because Joseph Heller couldn’t have been more accurate. For a critical element of our society, including many of the wealthiest and most powerful among us, there seems to be no limit today on what enough entails.

Getting close to 50k views and I'm wondering is it just everybody is scared to say this and pleased I did? Because if there's so many of us who agree, trust me I'd know if 1k people disagreed with me let alone 50k, why are we letting AI ruin our universities?

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n

Abstract: Under the banner of progress, products have been uncritically adopted or
even imposed on users — in past centuries with tobacco and combustion engines, and in
the 21st with social media. For these collective blunders, we now regret our involvement or
apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we
are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not
considered a valid position to reject AI technologies in our teaching and research. This
is why in June 2025, we co-authored an Open Letter calling on our employers to reverse
and rethink their stance on uncritically adopting AI technologies. In this position piece,
we expound on why universities must take their role seriously toa) counter the technology
industry’s marketing, hype, and harm; and to b) safeguard higher education, critical
thinking, expertise, academic freedom, and scientific integrity. We include pointers to
relevant work to further inform our colleagues.

Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI
(black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are
in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are
both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and
Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf.
Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al.
2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA).

Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms
are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

Spot on, and so glad @cenmag.bsky.social published this piece. I consider myself extremely lucky — in my PhD, I was well resourced, had a lot of freedom, and I worked in a mostly positive group culture. Still, I was horribly overworked and had severe mental health struggles. #AcademicSky ⚗️ 🧪 (1/4)

Absolutely - but my main issue is what the cold spots implies when used without context…. “If only a uni closer to them did the course they wanted, they would do it”… it ignores the institutional, class and generational barriers to higher Ed & certain subjects. Accessibility is not just geography

John O’Donoghue @drjohnodonoghue.bsky.social · 29d

So even though there is a great chemistry course only 30mins from me, it’s completely inaccessible without a car. So the only realistic option for a student from a low-income background is the 4 hour daily commute on the bus to Dublin…

John O’Donoghue @drjohnodonoghue.bsky.social · 29d

Basically it doesn’t matter where you live or how far, but are the supports in place to make it accessible? I live 30mins drive from a Uni, but there’s no public transport options there from where I live (i.e. you need a car), yet there is a regular bus option to all the Dublin universities (2hrs!)

John O’Donoghue @drjohnodonoghue.bsky.social · 29d

Closures are terrible and accessibility to courses are affected and should be highlighted - but I’m not sure if “commutable distance” is a great way of highlighting this when many people commute long distances already. Feels like a bit like an ivory tower way of looking at it

John O’Donoghue @drjohnodonoghue.bsky.social · 29d

Oh thank you, the @rsc.org have also used the term “cold spots” and I was curious if it’s a term that has been defined or not. I guess “commutable distance” can be very subjective

This is now the second use of the term “cold spots” I’ve seen in relation to commuting to university in the UK. What is the definition of a cold spot? Is it time or distance based? Either way, we have freezing spots in Ireland! 🤣 we have students & staff commuting across the entire country #HigherEd

This is one of the origins of the term “green room”. It may also be due to the huge popularity of green wallpaper & paint in the early 19th century following Carl Wilhelm Scheele's invention of copper arsenite green in 1775, which was removed a century later due to toxicity! #History #stage

A lens was used to concentrate the light from the flame into a beam to illuminate the performers. This is the origin of the phrase “in the limelight”. The resulting intense light had a slight green hue, and it is claimed that a room painted green would allow the actors to adjust their eyes #theatre
